Our focus
Cloudfonica was founded after field research across more than 35 voice markets examining real-world call termination bottlenecks: high last-mile transit costs, hardware licensing lock-in and opaque monthly billing commitments.
By moving RTP multiplexing, encrypted multi-tunnel transport and call filtering into an automated hourly cloud platform — and pairing it with lightweight router, Raspberry Pi and USB PC clients — Cloudfonica serves everyone from independent termination operators to wholesale carriers.
Our infrastructure spans seven low-latency data-centre co-locations across North America, Europe and Asia-Pacific so you can place media servers close to your signalling and termination endpoints.
